HINGE FOR SLIDING WINDOW SCREENS Filed March 9, 1925 y @QW PatentedSept.'` 17, 1929 UNITED STATES HINGE FOR SLIDING WINDOW SCREENSApplication led March 9, 1925.' Serial No. 14,288.

One of the objections to the sliding window screen as now most commonlyemployed is that it is necessary to bodily remove the screen from itsslides whenever it is desired to Wash the windows. Itis more or lessdiflicult to do this by reason of the weight of the screen, andfrequently the screen becomes overbalanced and falls to the ground whichresults in damage to the screen.

The object of my invention is to provide a combined sliding and hingescreen which may be easily installed and is of such construction thatthe cost will not materially eX- ceed the cost of the ordinary commonlyuse-d screen.

Another object of my invention is to pron vide in the place of the usualblind stops channel blind stops which serve the dual capacity of blindstops and slideways for the screen. n

A further object of my invention is to provide for use with the channelblind stops a screen frame having hinges, one leaf of which is adaptedto interlock with a slide in the said channel blind stops; and withthese and other objects in view, my invention consists of the parts andcombination of parts as will be hereinafter more fully set forth.

In the drawings:

Figure 1 is a front elevation of a window frame and its sash ywith myimproved screen mounted in said frame, the screen being shown in closedposition.

Figure 2 is an enlarged detail perspectivey view of one of the sidemembers of a window frame showing the'installation of my inventionthereto. f

Figure 3 is a sectional view through the lower portion of Figure 1.

Figure l is a perspective view ofmy improved hinge.

Figure 5 is an enlarged ydetail view.

Figure 6 is a perspective view of one of the slide pins.

Figure 7 is a perspective view of the face plate for said slide pins.

The reference numeral 1 designates a window frame having the sidemembers 2 and 3 and sill 4, all of which may be of the usualconstruction with the exception that I do not emplo the usual solidblind stops, but us'eiii place t ereof the blind stops and 6 construct-Af f ed of channel metal as clearly shown in Fig; ures 2 and 3. The blindstops are secured to the Window'frame by means of the screws, ory othersecuring devices 7. f f 1 1 i,

The blind rstop y5, as more clearly shown in Figure 3, is provided withan inwardly later.- ally extending flange 8 at the free edge of which.there is an inwardly extending fiange), theseflanges constitutingineffect a substantially L-shape flange, which term I may use in the claimfor the sake of clearness and brevity. The blind stopy 10 has one longarm or side member 11, which extension ofthe arm funct tions `as a guardcovering the joint between d the, blind stop and thehinge side ofthescreen 12, as more clearly shown in k,Figure 3. c i

At predetermined intervals in the rblind stop 10 I secure channelsections 13 and 14 l .the outer free edges ofthe side members of whichyare kbent inwardly at right angles to provide overhang flanges 15. Thesesectional channel' members may be secured in any suitable manner withinthe blind stop 10.` The channel section 13 is provided with a stopy 16yf to be hereinafter referred to. y vThe screen 12r is provided on oneofrits hanging stiles, the hinge 17, the leaf ,'18 ,of which is providedat each end witha liange 19 bent` inwardly at right angles to the leaf18, said flanges 19 having recesses 2() in each end thereof. The flanges19 may be described as substantially T shaped;

With `the hinges 17 secured to the screen 12 the screen is positionedwith the hinge' leaves 18 abovethe kupper edges of the chanf nelsections 13 and 14 whereupon the flanges y19 ofthe hinge leaf 18 arefree to'be pro jected withinthe blind stop Gwhereuponfthe y downwardkmovement of the screen causes the flanges 19 to movewithin thechannelsections f y13and lll, the flanges 15` of the channel sections 13andf14 interlocking in the recess 20 of theflanges 19 therebysecurelyinterlocking` the hinges in position within the blind I screen 12 frombinding on the window sill 4 I provide the stop 16 which is sopositioned as to hold the screen in the proper position relative to thewindow sill 4, as will be readily understood. In order to prevent thehinge leaves 17 and 18 from assuming intimate contact relation when thescreen is in its closed position I provide a stop 21 projecting abovethe tace ot the hinge leaf 17 and have shown this stop as being integralwith one of the screws to secure the leaf 17 to the screen frame.

On the other, or swinging side of the screen I provide slidable pins 22(preferably two in number) slidably mounted in the side stile of thescreen and adapted'aspshown in Figure 3, tobe projected Vwithin theblind stop 5. This pin is provided with a lock element 23 which,'asshown in Figure 3, will lock the pin 22 i-n-'its operative positionbyreason ot the fact that in that posit-ion the lock member 23 is atright angles to the slot 24 of the face -plate 25, which face plate issecured to the side 'stile of the screen. This pin 22, as shown inthedrawing, is provided with a suitable hand hold, as shown.

Now `with 'the parts yin the position shown in Figure 2 andin thesectional view of Figure 3 `the screen is in its position relative tothe window frame in which it may be swung outwardly on its hinges, afterthe bolts or pins y22 are withdrawn from the blind stop :5.` With theparts as shown in Figures l and 'the screen is in position to be slid inthe blind stops 5 and 6, and in order to hold the screen in the positionat the top of the window lframe I provide friction springs 26 whichare'secured in the bottom of the blind stop 5, said springs not onlyholding the screen' across the upperportion of the window frame, butalso exert the pressure in the direction of the hinged side ot thescreen therebyinsuring the'hinge in its proper seating and slidingaction.

'It will be understood that changes may be made in "the details ofconstructiony shown without departing from the scope of the appendedclaim.

What I claims is:

In a window, a'channel blind stop, a channel section secured in saidstop and having its outer edges bent inwardly toward each other, a hingeone 'leaf of which is provided with an inwardly bent yliange at eachend, a recess in each flange'adapted to receive the outer bent edges ofthe channel section and thereby lock the hinge on the blind stop.

In testimony whereof I aiix my signature.
